The table below offers suggested primers and alternative methods that commonly require primers,
adhesion promoters or other surface treatments for successful use with 3M™ VHB™ Tapes. This
list is not intended to be fully comprehensive but may be useful for many applications. It is very
important for the user to determine the suitability of the VHB tape, primer and application
process and compliance with local Air Quality Regulations.

• 3M™ Primer 94 and 3M™ Adhesion Promoter 111 is available through distributors that

carry 3M™ VHB™ tapes.

• 3M™ Scotch-Grip™ Plastic Adhesive 2262 must be thinned in acetone or MEK* in a 1:5 or

1:10 ratio (e.g., 1 part Scotch-Grip plastic adhesive 2262 to 5 parts acetone or MEK). The
product is available premixed in either acetone or MEK from: PRC DeSoto at (317) 290-1600.
3M™ Scotch-Grip™ Plastic Adhesive 2262T, thinned in 10:1 MEK solution or 3M™ Scotch-
Grip™ Plastic Adhesive 2262TA, thinned in 10:1 acetone solution.* When diluted in acetone
at this ratio, this material contains 196 g/l VOC.*

• Diluted 3M™ Scotch-Grip™ Plastic Adhesive 1099 must be thinned in acetone* in a 

1:3 ratio (e.g., 1 part Scotch-Grip plastic adhesive 1099 to 3 parts acetone). This thinned
material contains zero VOC’s when diluted in these ratios.

• 3M™ Adhesion Promoter N-200J is available from PRC DeSoto at (317) 290-1600.

• Silane Coupling Agent is available premixed in a 70:30 IPA/water solution or as a

concentrate. A 0.5 wt. % level of silane* adhesion promoter diluted in a 70:30 IPA/water
cleaning solution has been found to be sufficient.
